The ’ACT16620 are inverting 16-bit transceivers  
designed for asynchronous communication  
between data buses. The control-function  
implementation allows for maximum flexibility in  
timing.  
2OEAB  
2OEBA  
These devices can be used as two 8-bit  
transceivers or one 16-bit transceiver. They allow  
data transmission from the A bus to the B bus or  
fromtheBbustotheAbus, dependingonthelogic  
level at the output-enable (OEAB or OEBA)  
inputs. The output-enable inputs can be used to  
disable the device so that the buses are effectively  
isolated.  
The dual-enable configuration gives the transceiver the capability to store data by simultaneously enabling  
OEAB and OEBA. Each output reinforces its input in this transceiver configuration. Thus, when both control  
inputs are enabled and all other data sources to the two sets of bus lines are at high impedance, the bus lines  
remain at their last states.  
The 74ACT16620 is packaged in TI’s shrink small-outline package, which provides twice the I/O pin count and  
functionality of standard small-outline packages in the same printed-circuit-board area.  
The 54ACT16620 is characterized for operation over the full military temperature range of –55°C to 125°C. The  
74ACT16620 is characterized for operation from –40°C to 85°C.
